我遇到一个问题,我需要将某个实体中的字段(列)存储为xml数据类型,并使用jpa(eclipse链接)处理它们。
Does eclipse link provide a way to deal with xml other than no sql?
Does using no sql require the need of using different type of data
source and does that mean I cannot use a jta data source to deal with other normal entity?
Does using xml data type have bad impact on performance?
答案 0 :(得分:2)
如果你想在Eclipse中使用多个SQL(EclipseLink实现它),你应该看看JDO,一个更全面的持久性选项。 JDO用于许多类型的数据存储,如XML,NoSQL db等......
Google也使用JDO。
